SK760/SK880 System Exclusive Implementation
UNIVERSAL NON-REAL TIME SYSTEM MESSAGES
SAMPLE DUMP STANDARD
The transfer of data relating to the samples contained in the sounds of the instrument ias based on the standard protocol, called
SDS (Sample Dump Standard). The formats of the various commands available are as follows:
ACK (handshake message):
F0H = System Exclusive Message status
7EH = Non-Real Time extension
cc = device ID
7FH = ACK ID
pp = packet number
F7H = EOX
NACK (handshake message):
F0H = System Exclusive Message status
7EH = Non-Real Time extension
cc = device ID
7EH = NACK ID
pp = packet number
F7H = EOX
CANCEL (handshake message):
F0H = System Exclusive Message status
7EH = Non-Real Time extension
cc = device ID
7DH = CANCEL ID
pp = packet number
F7H = EOX
WAIT (handshake message):
F0H = System Exclusive Message status
7EH = Non-Real Time extension
cc = device ID
7CH = WAIT ID
pp = packet number
F7H = EOX

DUMP REQUEST:
F0H = System Exclusive Message status
7EH = Non-Real Time extension
cc = device ID
03H = DUMP REQUEST ID
ss ss = Request sample (LSB first)
F7H = EOX
device ID
Sample number (LSB first)
Sample format(# of significant bits from 8-28)
Sample period in nanoseconds (LSB first)
Sample length in words (LSB first)
Sustain loop start point word number (LSB first)
Sustain loop end point word number (LSB first)
Loop type (00=forward,01=backward/forward,7F=loop off)
